IMPROVEMENT lN BUG-DESTROYERS.

Specification forming part of Letters Patent No. 218,789, dated August19, 1879; application filed July 7, 1879.

To all whom it may concern:

Be it known. that I, RUFUS H. SPALDING, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a certain new anduseful Im provemen tin Bug-Destroyers, of which the following is a full,clear, and exact description.

This invention relates to potato-bug destroyers adapted to be strappedto the person and carried on the back; and it' consists of a reservoirprovided with one or more sprinklers and an interior stirrer arranged tobe reciprocately rotated therein from the movement of the arm of thecarrier. all as hereinafter described.

In the drawings, Figure l is a perspective view illustrative 'of themode of carrying and using this improved bug-destroyer; Fig. 2, a sideelevation in part, and vertical section in part; Fig. 3, a plan view inpart, and horizontal section in part.

In the drawings, A represents a reservoir, which, in the presentinstance, is shown of a cylindrical shape, and is to be made of sheetmetal or other suitable material, and adapted to be filled at a nozzleor other suitable inlet. This reservoir A is provided with strapssuitable for fastening it to the back of the personas, for instance, asshown in Fig. 1, and at or near the bottom, and on sides opposite toeach other it is provided with a flexible tube, a, and each tube at oneend communicates with theinside of the reservoir, and at the other endis provided with a sprinklencap, b. c is an upright central shaft withinthe reservoir A,

,and turning in suitable bearings thereof. This shaft within thereservoir has a series of horizontal arms, d, one above another. Thesearms (1 are fixed to the shaft, and the revolution of the shaft movesthem around within the reservoir, and thus the contents of the reservoirare stirred and agitated; and as it is intended for the purposes of theinvention to use in the reservoir paris-green, or any other suitablepoison, and water or other suitable liquid, this agitating of saidcontents by the said arms serves to prevent the settling of theparis-green to the bottom of the reservoir, and

to hold it in a state of suspension within the liquid, and thus in acondition to pass out with the liquid at the sprinklers b and bedistributed as desired. The shaftc passes out of the upper end of thereservoir A, and there it is provided with a horizontal pinion-wheel, 7,which engages with a vertical sector gearwheel, g, that turns on acenter-pin, h, of a fixed standard, B, and has pivoted to one of itsvertical faces one end, k, of a bent leverrod, l, which, at its otherend, m, is adapted, by a strap, a, or otherwise, to be strapped to thearm of the carrier below or above the elbow, as may be desired.

With this arrangement of mechanical parts the swing of the arm of thecarrier will re ciprocately rot-ate the shaft 0, and thus cause the stirand agitation of the contents of the reservoir, as hereinabovedescribed.

A reservoir, A, provided with sprinklers b and a stirrer or agitator, ashereinabove described, obviously enables the poisonous matters in thereservoir to be kept constantly mixed with and to be held insuspension-in the water while it is being carried about and distributedat the sprinklers at each side of the reservoir, and by having twosprinklers, one each side of the reservoir, obviously two rows ofpotatoes can be sprinkled by the person at one and the same time.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is-

p The combination, with a reservoir, A, which is adapted in any suitablemanner to be strapped to the back of a person, and is provided with asprinkler, b, and a vertical shaft, a, which has horizontal arms atwithin the reservoir, of gearing f g, connected with said shaft or, andof a lever-arm, l, pivoted to said gearing, and adapted to be strappedto and operated by the arm of the carrier, substantially as described,for the purpose specified.
